PRESS.

Application filed August 9, 1918.

To all whom it may concern:

Be it known that I, GEORGE LOUIS CAVA- LIERI, a subject of the King of Italy, residing at Somerville, in the county of MiddleseX and State of Massachusetts, have invented certain new and useful Improvements in Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art t0 which it appertains to make and use the same.

This invention relates to presses and more particularly to a press especially adapted for use in expressing the juice from grapes for making wine and for similar purposes.

One of the main objects of the invention is to provide a press of the character stated of simple construction and operation by means of which comparatively great pressure may be exerted so as to facilitate eX- prcssing juices from fruit being treated.

A further object is to provide a press in which the pressure disk is actuated by screw and lever means thus permitting great pressure to be exerted by the application of relatively small power.

Another object is to provide a press in which the operating screw may be rotated in either direction desired.

Further objects will appear from the detailed description.

In the drawings:

Figure l is a side view of a press constructed in accordance with my invention,

Fig. 2 is a central vertical sectional view through the press,

Fig. 3 is a section taken substantially on line 3-3 of Fig. 2,

Fig. 4 is an underneath view of the operating lever and disk and associated parts,

Fig. 5 isa detail end view of the operating lever showing the socket for receiving a handle to increase the length of the lever.

Fig. 6 is a detail perspective of the removable head, and

Fig. 7 is a fragmentary detail sectional view of the pawl for operating the operating disk and associated parts.

The numeral 1 designates a screw on the lower end of which is secured a disk 2 which tits snugly within a cylindrical vat or container 3 of'suitable construction. This disk is movable toward and away from a relatively thick head 4 provided with a depending peripheral iange 5. which ts Speccation of Letters Patent.

snugly about the upper end portion of the container 3, this head being provided on its upper surface with two diametrically opposite reinforcing members 5 provided with substantially rectangular recesses which snugly receive an angular flange 6 formed at the lower end of the hub 7 of an operating 'disk 8 through which and the hub the screw is threaded. By rotating the operating disk 8 in proper direction, the screw is threaded therethrough so as to move the disk 2 toward the head 4 exerting great pressure upon the grapes or other fruit positioned on the upper surface of the disk so as to eX- press the juices therefrom, these juices flowing through the perforations 2fL provided in the disk for this purpose, and being collected in a suitable receptacle at the lower end of 'the vat or container 3.

The periphery of the disk 8 is provided with a plurality of spaced substantially V- shaped notches or recessses which form spaced ratchet teeth 9. rIhese teeth are adapted to be engaged by the diverging fiugers 10, the ends of which are oppositely inl clined for this purpose, of a double acting pawl 11 pivotally secured by a pivot pin 12 on the under face of an operating lever 13 provided at its inner' end with an integral eye 14 which slidably receives the screw 1 and which rests upon the disk 8 and is therefore supported by the head 4. The outer end of the body of the pawl 11 is provided with an arcuate recess 14 curved on an arc concentric with the axis of a pivot pin 15 by means of which a spring latch 16 is pivotally secured to the under face of the lever 13 in a substantially V-shaped recess provided for that purpose, said recess being indicated by the numeral 17. The latch 16 is provided with a spring pressed plunger 18 which is adapted to engage the outer end of the body of the pawl 11 so as to hold the pawl in adjustment. By rocking the latch into its eXtreme position in either direction, the pawl may be readily adjusted and secured in adjustment, or, if desired, by turning the latch so as to bring the plunger 18 into alinement with the axes of pivot pins 12 and 15, the pawl may be held in inoperative position so as to permit free movement of the lever liabout the screw 1 independently of the operating disk 8. The lever is provided, at its inner end, with a relatively thick collar 19 secured on the upper face of the eye lil and slidably receiving the screw 1, this collar acting as a bracing and guiding member for the screw and "also as a weight member to hold the lever in depressed position. rlhis lever is further provided,

in its outer end with a polygonal socket 20.

:tor the reception oi a rod or handle 21, by means or which the effective length of the lever may be increased as desired, thus permitting the leverage exerted thereby to be greatly increased.

ln practice, the disk 2 is lowered so as to be spaced a comparatively great distance trom the under tace 0i: head d, after which the head and associated parts may be raised, the grapes being placed in the upper part or the container 3 so as to be supported upon the upper surface ot disk 2. After the desired quantity of grapes have been placed in the container, the head l andthe associated parts are lowered so as to bring the head into snug engagement with the upper end portion of the container', after which operating disk S is intermittently rotated by rocking the leverl 13 about the screw 1, in such direction as to cause upward movement of the screw, thus compressing the grapes between the head l and the disk 2 so as to express the juice therefrom. 'The combined lever and screw operating means for the disk 2 renders it possible to exert very great pressure upon the grapes by operating the lever 13 manually, thus insuring` that practically all of the juices will be removed from the grapes. By grasping the latch 16 and rocking it in proper direction, the pawl 11 may be readily adjusted so as to cause movement or' the screw 1 in either direction desired when the lever is oscillated. After the juice has been extracted from the grapes, the meat together with the skins and seeds which remain between the head l and the disk 2 may be readily removed by lifting the head a and the parts supported by it from the container 3, as will be evident. From the above description, it will be seen that a very simple and highly efficient press is obtained, inasmuch as the operating mechanism for ei'i'ecting bodily movement of the disk is mounted upon and supported by the head of the container, so that a very compact apparatus is obtained, in which the weight of the operating parts is added to the weight of the head to resist the pressure exerted by the Vdisk and the material thereon and avoids the necessity of fastening the head to the container.

l have herein shownV one construction embodying the invention but it is not desired to limit the invention to the particular construction shown.

Having thus described my invention, what l claim isz- 1. ln a press, a container normally open at its upper end, a dislr within said container to support the material to be pressed, a head to close said open end of the container, a screw connected with said disk and extended through said head, a toothed disl; mountedupon said head and provided with a hub through which said screw is extended in threaded engagement therewith, means attachedto said head and engaged with said hub to secure the latter to the head while permitting it to rotate thereon, and means supported by said head for rotating said tootheddisk.

iv. 1n press, a container normally open at its upper end, a disk located in said container and upon which the materials to be pressed are supported, a head to close the open end of said container and provided with reinforcing members having recesses,

a toothed disk provided with a huh having I a flange which engages the recessed reinforcing members to secure the toothed disk to said head while permittingit to be rotated thereon, a screw connected with said disk and extended through the said hub in threaded engagement therewith, and a lever supported by said toothed disk and through which said screw is extended, and a pawl carried by said lever and coperating with said toothed disk.

ln a press, a hollow container, a pressure disk located therein and upon which the material to be pressed is supported, a head mounted on the upper end oie said container to close the same, a screw slidable through said head and having its lower end secured to said disk, a toothed device rotatably mounted on said head and through which said screw is extended in threaded engagement therewith, means attached to said 'head and engaged with said device to secure the latter to the head while permitting it to rotate thereon, a lever mounted on said screw to oscillate thereon and supported by said toothed device to turn freely thereonv a weight attached to said lever over' said rotatable device to keep the lever in operative relation to the latter, a double acting pawl carried by said lever and cooperating with said toothed device to rotate the latter, and a spring latch carried by said lever and cooperating with said pawl to control the rotation of said toothed device by said pawl. ln testimony whereor" l afiix my signature in presence oi two witnesses.
